Vivian:
A more complete description is Sec 7, Block 28, Township 1N, Abstract 560, T&P RR Co. Survey. This abstract is located in approx. the middle of what would be the NW/4. There is no current production and there are two dry holes located in the SESESE & NWSWNE. One was drilled in 1983 and the other in 1987. No abstract leasing has taken place since 2009.
Can can also find a nice GIS map on the General Land Office of Texas website.

Just click on the: Launch GLO GISWEB Viewer link.
Search is top center of the map and you will need the county and abstract number only, drop the "A-".
